Benefits of technology

[0039]The transmission unit and the reception unit aligned along the reflection axis are preferably integrated into a module such that a simple and cost-effective design of the test device can be realized. As a result of this, it is possible to use two or more of the integrated modules, which are for example held by controllable mechanical arms. Here, the reception unit of one module can receive reflected test radiation from the same module and test radiation, transmitted from another module, along the transmission axis.

Problems solved by technology

The inspection of the carrier element becomes more difficult if it has a sheath.
This externally non-visible damage to the tension member constitutes a potential risk to safety.
A purely visual inspection by a servicing engineer therefore does not suffice.

Embodiment Construction

[0050]FIG. 1 shows a schematic illustration of an exemplary embodiment of an elevator installation 2, which has an elevator car 22 which can be displaced vertically in an elevator shaft 6 and is connected to a drive unit 23 via carrier elements 21 and a drive pulley 24. Further components of the elevator installation 2 (e.g. counterweight and safety apparatuses) or details in respect of the suspension of the elevator car 22 (e.g. 1:1, 2:1, etc. suspension) are not shown in FIG. 1 for reasons of clarity. However, it is understood that the exemplary embodiments described here can be used independently of these components or details, mentioned in an exemplary fashion, in the elevator installation 2.

[0051]The elevator installation 2 is furthermore provided with a test device 1 by means of which a carrier element 21 can be tested. In the illustrated exemplary embodiment, the carrier element 21 comprises a sheath 215 made of plastic in which, for example, two wire ropes 21A, 21B are integ...

Abstract

A testing device includes a receiving unit for electromagnetic signals arranged on a carrier element to be tested to generate test data from received electromagnetic radiation. The test data are evaluated in a processing system in order to determine a deviation of the test data from a nominal state of the carrier element. The testing device is used to test a carrier element of an elevator installation on which the elevator car is suspended.

Description

FIELD[0001]The invention relates to a method and a device for nondestructive testing of a carrier element in an elevator installation.BACKGROUND[0002]An elevator installation is installed in a building and substantially consists of a car which is carried by one or more carrier elements. In a known elevator installation a drive acts on the carrier elements in order to displace the car along substantially vertical guide rails. The elevator installation is used to convey people and goods over individual or a number of floors within the building.[0003]The carrier elements can be embodied as individual round ropes made of metal (steel). By way of example, each round rope has a diameter of approximately 8-10 mm and is stranded from individual strands, which in turn consist of individual wires. The round ropes are usually not sheathed, and so the stranding is visible on the surface thereof. Depending on the application, it is also possible for these carrier elements to be sheathed; then th...
